Putrescent Ascension

When Putrescent Ascension enters, until end
of turn, if you would draw one or more cards,
instead surveil 2, then draw that many cards.
Whenever a card is put into your graveyard
from anywhere, you may exile it.
For the purposes of spells and abilities you
control, you may treat any cards exiled with
Putrescent Ascension as if they were in your
graveyard.
